Hmm it might be worth checking that the MMC data lines are muxed
correctly. Maybe make sure CONFIG_OMAP_MUX_DEBUG is set in
your .config and CONFIG_DEBUG_FS too. Then boot and and mount
debugfs with mount -tdebugfs debugfs /sys/kernel/debug.
Then you can do:

# grep -i mmc1 /sys/kernel/debug/omap_mux/* | grep dat

And check the settings. Changing the values could cause data
corruption, so use a temporary root file system!
